The deeper memory develops like the disposition, or the native character, and like the understanding, as well as many other human faculties (see above [888]). For whatever gives the memory of personal matters its ability, is directly due to the inward memory, but [ultimately,] that power, regarded in itself, is a property of life. a] That there is a deeper memory, and what it is like, can be understood from the fact that in dreams, where the memory of personal matters is not so active as when one is awake, people normally appear with all their features, and every characteristic of their body, their speech, having the same walk, etc., more than the person [dreaming] had ever known from the memory of personal matters, nor could describe in such an abundance [of detail]. Similarly, we recognize people's moods or changing states of mind from their facial expressions, also from their eyes and the surrounding region, as well as from their tone of voice, and many more details beyond description. And people do not know where they learned to do this, except only from practice, without [previous] knowledge.
